how to add mixed number fractions?

Answer 1

Let's say you have 5 2/3. You'd multiply 5 by 3 and add that number to the numerator to get 17/3. Say you're adding that you 6 1/5 to that. 6 1/5 is 31/5. 31/5+17/3 is the same as 93/15+85/15 so it's 93+85=178 as the new numerator. You never add the denominator. So your answer is 178/15. To simplify that, you find how many times 178 goes into 15. It goes in 11 times and 15*11 is 165. There are 13 left over so the final answer is 11 13/15. Here are the steps more clearly written.

1. Multiply the whole number by the denominator and add that product into the numerator to make it a single fraction.

2. Find a common denominator and convert both fractions into fractions with that denominator.

3. Add the fractions together. Find how many times the numerator goes into the denominator. That is your new whole number. What ever is remainding is your numerator. Simplify that fraction.

4. Good luck!

Answer 2

change it to a prpoer fraction so if the number is 3 3/4 it becomes 15/4 ( you times your bottom number by the whole number , add the numerator and then put that number over your orignal denominator) then find the lowest common denominator times it throughout and add it all up! Goo dluck i sucked at fractions and now i tutor kids who need help! The irony!

Answer 3

you could convert the two mixed numbers into incorrect fractions. 5 one million/2 + 3 one million/4 = 11/2 + thirteen/4 Now locate the time-honored denominator. 11/2 + thirteen/4 = 22/4 + thirteen/4 22/4 + thirteen/4 = 35/4 = 8 3/4. the respond is 8 3/4.

Answer 4

you change them in to not mixed fractions and then you add them.

Answer 5

covert them to improper fractions then you find a commomn denominator and add
